Abstract: This invention relates to rear view mirror assemblies. 
     Figure  1  shows a rear view mirror assembly, generally indicated at 10, having a mirror 12. A wiper blade 15 is mounted on an arm 16 to wipe across the surface of the mirror 12. The arm 16 is mounted by means of a movable carriage 18 on a double helical screw 19. The double helical screw 19 is drivingly connected to a motor 22. The carriage 18 engages the helical screw 19 such that on rotation of the screw 19 the carriage 18 is driven axially back and forth along the screw 19. This movement causes the wiper blade 15 to be swept across the surface of the mirror 12 within the area of delineated by the line 37. 
     Alternatively, the carriage 18 may be driven by a single-handed lead screw, the direction of rotation of the motor being reversed each time the wiper blade 15 reaches the end of a sweep across the mirror 12. 
     Thus, the wiper blade 15 and arm 16 can be parked to one side of the mirror 12 where they do not obstruct the central portion of mirror 12. 
     It is particularly envisaged that such rear view mirrors would be used on trucks and other commercial vehicles.

Abstract: Apparatus is disclosed for induction heating of metallic pipelines either in a weld area to effect a heat treatment or a pre-fusion coating temperature increase, at a pipe end or along the whole length of the pipe in order to effect drying. Apparatus for pre-coating temperature increase comprises a frame 10 whose essentially semi-circular cross-section members 11 and 12 are each made up of aluminium end plates 13, 14,15 and 16. Aluminium box-section cross members secure the end plates together and mounted to the radially inner surfaces of these cross members are aluminium strip conductors 48 and 49 which in use clear the surface of a pipeline about which the apparatus is received. In operation, primary current passing through the ribbon-like conductors induces a secondary heat-generating current in the pipeline raising its temperature to as high as 750°C when using an electrical supply of 180 volts, 2500 amps and nominal frequency of 3500 hertz. The induction heater can be placed overthe pipeline or removed from it by hinging apart of the two frame members 11 and 12 at a jaw of the apparatus.

Abstract: An antiskid braking system includes an improved apparatus for generating a lead signal to provide lead compensation. According to one feature of this apparatus the gain is a function of the algebraic sign of the input signal to the apparatus. Preferably, higher gains are used when the input signal corresponds to wheel deceleration than when it corresponds to acceleration. Another feature of the invention is that the apparatus operates to reduce the magnitude of the lead signal when it exceeds a limit value, preferably by clamping the lead signal to a maximum magnitude.

Abstract: A cathode ray dual mode electromagnetic beam deflection amplifier system for providing current for driving a deflection coil (70), and means (40) for switching between linear and resonant non-linear operational modes. In the linear mode, the deflection coil current is controlled closely to follow an applied input deflection sweep voltage and operates as a push-pull amplifier. In the non-linear resonant mode, one-half of the output stage is abruptly decoupled from the deflection coil (70) such that energy stored in the deflection coil is discharged into a series capacitor (28), the subsequent resonant pulse being returned through the non-decoupled half of the output stage to a power supply.

The MOS transistors aligned in each of the rows have one common gate electrode (40A and 40B) which extends over a row of the field insulation films (22). The MOS transistors aligned in each of the rows have a common first region (17) for forming a drain (36) or a source (37) extending parallel to the common gate electrodes (40A and 40B) and second regions (16) for forming the other of the drain or source are surrounded by a pair of common gate electrodes (40A and 40B) and a pair of field insulation films (22) so that the plurality of second regions are isolated from each other. The edges of the field insulation films (22) and of the common gate electrodes (40A and 408) facing the common first region (17) are coincident. This can be achieved by using a mask film (26) extending between and covering the region between a pair of common gate electrodes and the part of the common gates not covered by the masking film (26) as masks and carrying out an etching process.

Abstract: An adhesive web is to be pressed on to the edge of a shaped sheet metal part, so that the web portion on the metal part has a U-shaped cross-section. To this end, the adhesive web is first peeled off a carrier tape and is then folded with the aid of a deflecting and pre-folding roller having a profile whose cross-section is a wide V. The pre-folded web is then folded further continuously in a funnel-shaped pre-folding channel. The sheet metal part whose edge is to be covered is then introduced with that edge, within the reach of the pre-folding channel, into the folded bend of the adhesive web, and both the sheet metal part and the web thereon are conveyed together by a pair of feed and press-on rollers which press the adhesive web on the edge and sides of the sheet metal part.

Abstract: A method for selectively heating an insulating layer on a semiconductor structure by a high energy transient radiation source to a temperature sufficient to cause reflow without any significant heating of the regions adjacent to or underlying the insulating layer. In one embodiment a laser tuned to the absorption wavelength of the insulating material is scanned over the surface of the semiconductor structure. In another embodiment an insulating layer and an underlying or adjacent semiconductor layer are concurrently heated by a laser tuned to an absorption wavelength common to both in order to maintain the integrity of the interface therebetween. In a further embodiment the depth of heating in an insulating layer is controlled by selecting an appropriate dwell time for a continuous wave laser and a pulse duration for a pulsed laser.

Abstract: An electromagnetic detector device embodying a linear voltage differential transformer. A pair of coils of the differential transformer serve as pick-up coils connected in a detector circuit which is phase sensitive and capable of discriminating between signals representing a target metallic material, such as carbon steel particles trapped in a filter element, and signals induced by other metallic material, as well as stray signals including electrical noise. Input signals representing a target metallic material are fed to an operational amplifier circuit including a first non-inverting amplifier and a second inverting amplifier which produce a non-inverted signal and an inverted signal which are fed to an analog switch. The switch is operated as a chopper by a driver signal having a predetermined phase and the same frequency relative to the signal driving an input coil to the transformer. The phase of the driver signal is adjustable to provide phase discrimination. The coils of the transformer are wound on a core providing a sensor in which a filter element may be placed for test.

Abstract: A ceramic product (10) is exposed to a light from a tungsten lamp (50), so that a specified region of the product is heated. In this heating process, acoustic emissions from the ceramic product (10) are detected by an AE sensor (16) which is acoustically coupled to the ceramic product (10) by means of a waveguide passage (14). A temperature gradient directed from the surface toward the inner part of the ceramic product (10) is formed by heating, and thermal stress is applied to the product (10) so that tensile stress is produced in the inner part of the product. In practical use, a crack constituting the core of fracture is caused to grow by the thermal stress, and an acoustic emission is released. The existence of a defect can be evaluated by detecting the acoustic emission. Also, the location of the defect in the product can be detected by heating part of the product. The equivalent crack dimension a e  of the defect is obtained by measuring the rate of production of acoustic emission dN/dt, and the product can be checked for acceptability on the basis of the dimension a e .
